Hindi ka mag-aalala, normal lang yan! Usually around 4.5 to 5 months pa lang when moms start feeling kicks, lalo na if first baby mo kasi sometimes you don't know what to expect pa, so you might miss the light flutters, one of my mum friends thought it was lang gas haha. You could feel it anywhere from now to next month, everyone's different talaga, so just relax and wait lang, it's coming soon!
